Abstract
Test samples of genomic DNA may be characterized by the use of polynucleotide probes each of which is specific for an informative genetic locus. Such probes may be prepared by the use of probes which are capable of differentiating DNA by reference to more than one polymorphic minisatellite region or hypervariable locus. The polynucleotides and probes of the invention are of use for genetic identification purposes, paternity and maternity testing and particularly in forensic medicine.
Description
The present Invention relates generally to polynucleotides and DNA and RNA probes, their preparation and their use in genetic characterisation. Such uses may include for example establishing human, animal or plant origin, and che polynucleotides and probes of the Invention may thus find use for example in paternity disputes or forensic medicine or in the prevention, diagnosis and treatment of genetic disorders or predispositions.
In Patent Specification No. there are described various DNA sequences which may be used as probes to hybridize Individually at a number of polymorphic sites within the human and animal genomes enabling the production of a fingerprint** composed of marked bands of differing molecular weights. The fingerprint as a whole is characteristic of the individual concerned and the origin of the differing bands can be traced through the ancestry of che individual and can in certain cases be postulated as associated with certain genetic disorders.
The present Invention is based upon the discovery that informative genetic loci may be identified in the genome by the use of multi-locus probes and that polynucleotides and polynucleotide probes may be prepared each of which is specific for a single such informative genetic locus.
Hitherto, only, a limited number of hypervariable loci have been discovered in human DNA; these Include mlnisatelllces 5* to the insulin gene (Bell, Selby and Rutter, 1982), 3' to the c-Ha-rasl gene (Capon et al., 1983), type II collagen gene (Stoker et al.. 1985) and between the ζ2 and kijl globin genes (Goodboutn et al., 1983) as well as the D14S1 locus defined by an anonymous DNA clone derived from the telomeric region of the long arm of chromosome 14 (Wyman and White, 1980; Balazs et al., 1982; Wyman, Wolfe and Botstein, 1984). These minisatellites differ substantially in their variability, ranging from only 6 different alleles detected at the collagen hypervariable region (Sykes, Ogilvie and Wordsworth, 1985) to more than 80 at the D14S1 locus (Balazs et al., 1986). The total number of hypervariable loci in the human genome is unknown but is likely to be large. Indeed the human genome might contain at least 1500 hypervariable regions.
It has been found that it is possible to clone a DNA fragment Identified by hybridisation of fragments of genomic DNA with a polynucleotide probe capable of differentiating DNA by reference to more than one polymorphic .minisatellite region or hypervariable locus, for example the probes 33.6 and 33,15 described and claimed in the Patent Specification No. and to prepare therefrom a polynucleotide or probe capable of hybridising to a DNA fragment which contains a minisatellite which is specific as to a particular region or locus on the genome, said region or locus being an Informative genetic locus. In this specification we define an informative genetic locus as one at which at least 3 different alleles can be distinguished in any sample of 100 randomly selected unrelated individuals. This is expressed herein by stating that the locus has an allelic variation of at least 3(100). Preferably the sample of randomly selected unrelated individuals will be 500, more preferably 1000, and the ability to distinguish at least 3 different alleles in such samples is referred to herein as 3 (500) and 3(1000) respectively. It is essential that the sample of 100, 500 or 1000 randomly selected unrelated individuals is indeed selected at random as lt will usually be possible to identify 100, 500 or 1000 individuals who have less chan 3 alleles at a given informative genetic locus by screening a sufficiently large number of members of the total population. f The higher is this polymorphism at a given Informative genetic locus, the more useful and informative V will be the locus specific probe in genetic characterisation for example in individual identification for paternity or forensic evaluation.
It will be appreciated in this regard that the term individual has been used above to refer not only to humans, but also to other animals as well as to plants and to cell lines derived from such humans, animals and plants. In each case, however the sample of randomly selected unrelated individuals will all be from the same species.
In respect of the human applications of the present invention the expression informative genetic locus as used herein may alternatively be defined as one at which -at least 3 different alleles can be distinguished in DNA extracted from any 2C cell lines selected from those listed below.
This is expressed herein by stating that the locus has a degree of polymorphism of at least 3.

The invention includes labelled polynucleotides in ss-form for use as probes as well as their labelled dsprecursors, from which ss-probes can be produced.
Thus according to a further feature of the present invention there is provided a polynucleotide probe which comprises a polynucleotide of the present invention as hereinbefore defined or a polynucleotide prepared by a method as hereinbefore defined having a labelled or marker component. Generally at least the nucleotide sequence of the polynucleotide will be in single stranded form, but preferably the probe will comprise the polynucleotide wholly in single stranded form.
According to a further feature of the present invention there is provided a method of preparing a polynucleotide probe as hereinbefore defined which comprises labelling or marking a polynucleotide of the present invention as hereinbefore defined or a polynucleotide prepared by a method of the present Invention as hereinbefore defined.
The polynucleotide probes of the present invention are preferably ^P-radiolabelled in any conventional way, but can alternatively be radiolabelled by other means well known 0 in the hybridisation art for example to give 35s— radiolabelled probes. They may also be labelled with biotin / or a similar species by the method of D C Ward et al, as described in Proceedings of the 1981 ICN—UCLA Symposium on * Developmental Biology using Purified Genes held in Keystone, Colorado on March 15-20, 1981 vol. XXIII 1981 pages 647-658 Academic Press; Editor Donald D Brown et al or even enzymelabelled by the method of A D B Malcolm et al.

The method of the present invention is preferably 10 effected by'the use of a polynucleotide or a polynucleotide prefered by a method of the present invention or a polynucleotide probe of the invention as hereinbefore defined.
Preferably the sample DNA is human DNA.
In order to assist the reader the following the present specifIcation:Hypervariable A region of human, animal or plant DNA at a recognised locus or site is said be hypervariable if it occurs in many different forms e.g. as to length or sequence.
Mlnlsatelllte A region of human, animal or plant DNA which is comprised of tandem repeats of a short DNA sequence. All repeat units may not necesarlly show perfect identity. Polymorphic A gene or other segment of DNA which shows variability from individual to individual or between a given individuals paired chromosomes is said to be polymorphic.
Repeat or Tandem Repeat (Sequence) A polynucleotide sequence which is perfectly or Imperfectly repeated in series. In general a sequence which 2 ls said to be tandemly repeated will be repeated at least three times. z Imperfect Repeat (Sequence) A sequence which is not an exact repeat either as V to number or kind of nucleotides but recognisably a repeat of a consensus sequence.
Homology In comparing two repeat or tandem repeat sequences A and B, the percentage homology is given by the number of base pairs in A less the number of base pair substitutions, additions or deletions in B which would be necessary in order to give A, expressed as a percentage. Thus the percentage homology between two sequences ATGC and AGC is 752.
Consensus Core (Sequence) A sequence which can be identified as the closest match among a number of repeat sequences; usually among the repeat units of two or more different minisatellites.
Nucleotide (nt) and base pair (bp) are used synonimously. Both can refer to DNA or RNA. The abbreviations C, A, G, T refer conventionally to (deoxy)cytidine, (deoxy)adenosine, (deoxy)guanosine and either deoxythymidine or uridine. It will be appreciated however that the abbreviations A, C, G and T may include other base modified nucleosides capable of base pairing with one of the conventional nucleosides (deoxy)adenosine, (deoxy)cytidine, (deoxy)guanosine and either deoxythymidine or uridine. Such base modified nucleoside include (deoxy) inosine and (deoxy)8-azaguanosine.
Where the polynucleotide or polynucleotide probe of * the present invention comprises a tandemly repeated sequence, ΐ the tandem repeats may be perfect repeats or Imperfect 3 repeats or a mixture of perfect and imperfect repeats. There are preferably at least three repeats and more preferably at least 7 repeats in the probe sequence.
The probes of the invention which may be used singly or in combination with other locus specific probes either in a sequence of tests or in a single test using a mixture or cocktail of probes may be useful in the following areas: 1. Paternity and maternity testing in man. 2. Family group verification in e.g. immigration disputes and inheritance disputes. 3. Zygosity testing in twins. 4. Tests for inbreeding in man.
. General pedigree analysis in man. 6. Identification of loci associated with genetic disease in man, thereby enabling specific probes to be constructed to detect a genetic defect. 7. Forensic medicine, for example (a) fingerprinting semen samples from rape victims (b) fingerprinting blood, hair and semen samples from e.g. soiled clothing (c) identification of human remains. (4) characterisation of other forensic tissue samples e.g. skin. 8. Cell Chimaerism studies, e.g. following donor versus recipient cells after bone marrow * 30 4 transplantation. 9. Livestock breeding and pedigree f analysis/authentication. (This could include, for example, the routine control and checking of pure ? strains of animals, and checking pedigrees in the case of litigation involving e.g. race horses and dog breeding). Also to provide genetic markers which might show association with inherited traits of economic importance.
. Routine quality control of cultured animal or plant cell lines, checking for contamination of pure cell lines and for routine identification work. 11. Analysis of tumour cells and tumours for molecular abnormalities. 12. It is anticipated that the polynucleotides or probes derived therefrom have a potential use in plant breeding.
The locus specific probes of the present Invention are, however, particularly useful in forensic medicine as demonstrated in Example 3 hereinafter and at least the probe pAg3 may cosegregate with the heterocellular form of hereditary persistence of foetal haemoglobin. The probes also provide a powerful method for use in paternity testing and related utilities (see utilities 2 and 5 above) as well as in cell chimaerism studies.

The polynucleotides of the invention, polynucleotides prepared by the processes of the Invention and probes of the present invention are capable of hybridising with fragments of DNA containing a minisatellite from a single specific minisatellite region or hypervariable * locus and are thus locus specific. In general the fi polynucleotides and probes of the present invention will be locus specific under high stringency hybridization conditions. In this regard the expression locus specific is used herein in relation to a polynucleotide or probe to mean that the polynucleotide or probe may be used under hybridization conditions which ensure that the polynucleotide or probe hybridises to only a single specific locus.
It will be appreciated, however, that the locus specific probes of the present invention when used at reduced hybridisation stringencies may be capable of differentiating DNA by reference to more than one polymorphic minisatellite region or hypervariable locus and may thus be used to identify other informative genetic loci.
Thus according to a further feature of the present invention there is provided a method of preparing a polynucleotide capable of hybridising to a DNA fragment which contains a minisatellite which is specific as to a particular region or locus in the genome, said region or locus having an allelic variation (as herein defined) of at least 3(100), which method comprises cloning a DNA fragment identified by hybridisation of fragments of genomic DNA with a polynucleotide probe as hereinbefore defined and preparing therefrom a polynucleotide capable of hybridising to a DNA fragment which contains a minisatellite which is specific as to a particular region or locus on the genome, said region or locus having an allelic variation (as herein defined) of at least 3(100); the method being effected under hybridisation conditions effective to render the probe capable of differentiating DNA by reference to more than one polymorphic mlnlsatellite region or hypervariable locus.
According to a further feature of the present invention there is provided a polynucleotide, in isolated or 8 cloned form, which comprises a nucleotide sequence which is specific as to a single minisatellite region or hypervariable f locus and which is homologous therewith to a degree enabling hybridisation of the nucleotide sequence to a corresponding « DNA fragment obtained by fragmenting sample genomic DNA with a restriction endonuclease, the said DNA fragment containing a minisatellite from said minisatellite region or hypervariable locus, wherein:— 1) said region or locus has an allelic variation (as herein defined) of at least 3(100) and 2) said region or locus Is detectable by a locus specific polynucleotide probe as hereinbefore defined.
The invention also relates to a corresponding method and to a corresponding polynucleotide In which the said region or locus has a degree of polymorphism of at least 3.
The invention further relates to probes comprising such locus specific polynucleotides and to a method of characterising a test sample of DNA using such polynucleotides and polynucleotide probes.
The locus specific polynucleotides and probes of the present invention may be homologous with the minisatellite of the minisatellite containing DNA fragment or less preferably with a sequence flanking the minisatellite.
Where the polynucleotides and probes of the present invention comprise tandem repeats of a particular sequence such sequence will in general be repeated at least 3 times and such repeats need not necessarily be exact repeats.
Repeats which are not exact are described elsewhere as * imperfect repeats. Such repeats will nevertheless be ΐ recognisably repeated. In general this will mean that there is on average at least 701 homology between all repeating units. Preferably there is at least 80S, more preferably at least 85S, especially 90S homology between all repeating units. It will be appreciated however that the nucleotide sequence or repeat unit need not be repeated at all if desired.
The number of repeat units, n, is advantageously at least 5, but preferably ac least 10. Conveniently n is 10 to 40, but in principle n can be any number, even from 1 up to 10,000.
Where the polynucleotides and probes of the present Invention comprise tandem repeats of a particular sequence, any flanking sequences are largely irrelevant. They can be omitted or can be present in any number of nucleotides, for example up to 50,000 although to work with such a long probe would not ordinarily be sensible. Such large polynucleotides may nevertheless serve as carriers from which smaller polynucleotides, especially useful as probes, may be excised. These flanking sequences may form part of either ds—DNA or ss-DNA, even when the repeat sequences are of ss-DNA.
Preferably the polynucleotides and polynucleotide probes of the present invention comprise any one sequence selected from formulae 3 to 9 as hereinbefore defined or a sequence complementary thereto or tandem repeats thereof (there being on average at least 70Σ homology between all tandemly repeated sequences) or a sequence complementary thereto.
One preferred polynucleotide of the present Invention thus comprises the sequence of formula 3 as hereinbefore defined or tandem repeats thereof or a sequence complementary thereto. Such a nucleotide sequence is specific as to an autosomal locus located on chromosome 7.
Polynucleotides and polynucleotide probes comprising such a sequence are referred to herein as pAg3.
A further preferred polynucleotide of the present invention comprises the sequence of formula 4 as hereinbefore defined or tandem repeat(s) thereof or a sequence complementary thereto. Such a nucleotide sequence ls specific as to a locus located on chromosome 1. Polynucleotides and polynucleotide probes comprising such a sequence are referred to herein as λ MSI.
A further preferred polynucleotide of the present invention comprises the sequence of formula 5 as hereinbefore defined or tandem repeat(s) thereof, or a sequence complementary thereto. Such a nucleotide sequence ls specific as to a locus located on chromosome 7. Polynucleotides and polynucleotide probes comprising such a sequence are referred to herein as AMS31.
A further preferred polynucleotide of the present invention comprises the sequence of formula 6 as hereinbefore defined or tandem repeat(s) thereof or a sequence complementary thereto. Such a nucleotide sequence ls specific as to a locus located on chromosome 1. Polynucleotides and polynucleotide probes comprising such a sequence are referred to herein as AMS32.
A further preferred polynucleotide of the present Invention comprises a sequence selected from formulae 7 and 8 as hereinbefore defined or tandem repeat(s) thereof or a sequence complementary thereto. Such a nucleotide sequence ls specific as to a locus located on chromosome 5.
Polynucleotides and polynucleotide probes comprising such sequences are referred to herein as AMS8.
A further preferred polynucleotide of the present invention comprises the sequence of formula 9 as hereinbefore 1 defined or tandem repeat(s) thereof or a sequence complementary thereto. Such a nucleotide sequence is specific as to a locus located on chromosome 12. Polynucleotides and polynucleotide probes comprising such a sequence are referred to herein asAMS43.
As Indicated above there is in general at least 70%, advantageously at least 802, preferably at least 352 and most preferably at least 902 homology between repeat units.
It is especially preferred however that any one of the sequences of formulae 3 to 9 be repeated exactly. In this regard it will be appreciated that this latter requirement may be met provided that each repeat unit has a sequence falling within the scope of the desired formula; it is thus not necessary that each repeat unit possesses exactly the same sequence.
In a preferred embodiment of the present Invention there is provided a method of establishing the Identity or otherwise of the test sample donor with one or more control sample donors, in which the control sample(s) are similarly fragmented and a comparison is made of the hybridised fragments from the respective samples.
In a further preferred embodiment there is provided a method of establishing a family connection between the test sample donor and one or more control sample donors, in which the control sample(s) are similarly fragmented and a comparison is made of the hybridised fragments from the respective samples.
The above-mentioned methods may be effected using the polynucleotides or probes of the present invention either singly or by using at least two polynucleotides or probes of the present invention either in a sequence of tests or in a single test using a mixture of the said polynucleotides or probes.
In a further preferred embodiment of the present invention there is provided a method for the diagnosis of an inherited disease, abnormality or trait which comprises ί probing the test sample with at least one polynucleotide or polynucleotide probe as hereinbefore defined, said probe, being associated with a particular inherited disease, abnormality or trait.
The probes of the present invention which we have tested all serve as locus—specific probes under high stringency hybridization conditions.
The extreme variability of loci detected by those probes of the present invention which we have tested, combined with their sensitivity in Southern blot hybridizations, provide an especially useful tool in individual identification, particularly when Insufficient DNA is available for multi-locus DNA fingerprinting analysis as described and claimed in Patent Specification No.it'5' ss multi-locus DNA fingerprints can be obtained from 0.5 pg DNA, whereas the locus—specific probes are at least an order of magnitude more sensitive and can be used on as little as 1 μΐ blood.
In any unusual situation where even smaller quantities of sample might require testing then the present invention will be particularly valuable in conjunction with the amplification technique described in European Patent Application No. 86302299.2 (Publication No. 0201184).
The present invention enables informative genetic loci to be identified in the human genome and thereby enables locus specific probes to be prepared, each locus specific probe being specific as to a single informative genetic $ locus. We have specifically identified six different very 3 informative genetic loci, which loci possess very high heterozygositites in the population tested (at least 902) and which are amongst the most polymorphic so far isolated . and we have prepared a locus specific probe for each locus 5 which probes we have designated pAg3, AmSI, AmS8, AMS31, /MS32 and AMS43 (as hereinbefore defined).
The degree of individual specificity of genotypes determined by locus—specific probes can be estimated from the heterozygosity H at each locus. The mean allele frequency q at a locus is given by (1—H), and the probability that two randomly-selected individuals share the same genotype is q2(2-q). This probability of false association of two individuals varies from 0.02 for ^Mse ot 0.0002 forAMS31, and is a conservative estimate in that heterogeneity in q will reduce these probabilities. The cumulative probability of false association for all six minisatellite probes is λζ10"16, comparable to the odds that two randomly-selected DMA fingerprints detected by one multilocus probe are Identical (see Patent Specification No.2.bitted) . In contrast the chance that two slbs are identical for a given hypervariable locus is given by lZ4(l+q)2. The cumulative probability of sib identity for all six probes is 0.0004, compared with 'ΊΟ-7 for a DNA fingerprint using one multilocus probe.
These locus-specific hypervariable probes should prove particularly useful in forensic medicine, as shown by the murder case analysed in Fig. 11C where insufficient DNA was recovered from two of the forensic samples for DNA fingerprint analysis. Semen DNA from both victims showed a common phenotype with probes AMSl and AMS31 different from that of the suspect. From the above discussion, we can calculate the probability that victims X and Y had been 4 sexually assaulted by different unrelated men at 2xl0~^.
Similarly, the chance that the two hypothetical assailants were first—degree relatives, for examples brothers, is 0.07.
This provides strong evidence that X and Y were sexually » assaulted by the same man, a conclusion which was subsequently confirmed by DNA fingerprint analysis of larger amounts of forensic material. Furthermore, the semen stains from X and Y are almost certainly derived from a single individual, rather than two or more assailants. Consider for example stain b in Fig. 11C, which shows two victim alleles and two additional assailant alleles. The chances that a pool of three individuals (two assailants and one victim) would show four or less resolvable alleles is given by q2 (55-21Oq+216q2). For probe MSI, this probability is 0.02 and for probeAMS31 0.005, giving a combined probability that X was sexually assaulted by two men, rather than one, of -4. This establishes that X and Y were assaulted by a single individual, and shows that locus—specific probes, unlike multi—locus DNA fingerprint probes, can be used to estimate the number of individuals represented in a mixed DNA sample.
The Mendelian inheritance of the hypervariable DNA fragments also allows them to be used for establishing family relationships in for exaaple paternity disputes. For a given locus—specific probe, the probability that a child's paternal allele is fortuitously present in a randomly—selected man can be estimated at 2q—q^. For all six minisatellites, the cumulative probability of false inclusion of a non-father is 6 Tf (2q^—qj2)-107, comparable to that obtained using two DNA 1 fingerprint probes. Similarly, the cumulative probability of false inclusion of a first degree relative of the true father, such as a brother, is 0.02. Thus sequential use of these hypervariable locus—specific probes can provide a powerful method for establishing family relationships with the caveat that mutations to new length alleles at these unstable loci could occasionally lead to false exclusions.
The mutation rate at these hypervariable loci is not yet known.
The locus—specifIcity and sensitivity of these locus—specific probes enable pooled probes to be used to generate multi-locus Southern blot patterns (Fig. 12). These reconstituted DNA fingerprints produced by 5 pooled probes are considerably less complex than their counterparts detected by multi-locus probes, and should be more amenable to being encoded digitally following densltometric scanning. Despite the high variability of the individual minisatellites, the pooled-probe profiles show a substantial (182) level of fragment sharing between unrelated North European individuals, mainly as a result of electrophoretic comigration of mlnlsatelllte fragments from different loci. This level of band sharing is similar to that seen in conventional DNA fingerprints produced by multi—locus probes, where the level of band sharing is^SZ between randomly-selected individuals. Since on average 8.4 DNA fragments are resolved in a mixed—probe pattern, the chance that all of these fragments in one individual are present in a second randomly—selected individual can be conservatively estimated at 0.18θ·4 » 6x10"?. These patterns therefore provide a high level of Individual specificity, though not as high as can be achieved using multi—locus probes or by sequential hybridization with locus—specific probes (see 6 above). Both the pooled probes and individual locus—specific probes will prove particularly useful in studies of cell chimaerism, particularly for providing donor versus recipient markers for following engraphment after bone marrow transplantation; DNA mixing experiments (Fig. 12) indicate that low levels of chimaerism could be detected using these probes.
In the following Examples temperatures are given in °C and the probes 33.6 and 33.15 are as described in Patent Specification No. having the consensus repeat sequence;— (A)AGGGCTGGAGG, and AGAGGTGGGCAGGTGG respectively 2? Example 1 This Example describes the isolation and properties of a specified minisatellite fragment in a DNA fingerprint. General methods DNA was isolated from white blood cells as described by Jeffreys A J et al, (1985) Nature 316, 76—79 and from an Epstein Barr virus transformed lymphoblastoid cell line (see Nilsson, K et al (1971) Int. J. Cancer 8, 443—450) derived from individual III 9 of the HPFH pedigree described by Jeffreys et al.. Am. J. Hum. Genet. 39, 11—24.
Restriction digestion and Southern blot hybridizations were performed as described elsewhere in the above-mentioned references of Jeffreys A J et al. Double-stranded DNA probe fragments were isolated by electrophoresis onto DE81 paper as described by Dretzen, G et al (1981) Anal. Biochem. 112, 295— 298 and labelled with 32p by random oligonucleotide priming as described by Feinberg, A P et al (1984) Anal. Biochem. 137, 266—267; single-stranded minisatellite probe 33.15 was prepared as described by Jeffreys et al (1985) Nature 314, 67-73.
Cloning hypervariable fragment g 600 pg individual III 9 lymphoblastoid cell line DNA digested with Sau3A was fractionated by electrophoresis through a 0.52 agarose gel, and relevant size fractions collected by electroelution onto dialysis membrane as described in Yang, R C A et al, (1979) Meth. Enzymol, 68, 176—182. After two cycles of preparative gel electrophoresis fragment g was 1000 fold purified (yield 150 ng DNA). 20 ng of this partially purified fraction was ligated to 60 ng AL47.1 arms isolated after cleavage with BamHI (see Loenen, V A M and Branmar, W J (1980) Gene. 20, 249—259) packaged in vitro and plated onto E. coll WL95 (803, supE, supF, hsdRif*, hsdMk*. tonA, trp?-, metg, lysogenic for P2) [see Loenen reference above and Jeffreys, A J et al (1982) J Mol. Biol. 156, 487—503] to select for recombinants. The resulting library of 1500 recombinant phage was screened by plaque hybridization with minisatellite probe 33.15. Four positive plaques were replated and rescreened on E. coll ED8910 (803, supE, supF, recB21. recC22. hsdS) [see Loenen reference above] and recombinant phage DNA prepared by the method of Blattner et al (1977) Science 194, 161—169. The Sau3A Insert of recombinant phage g3 was subcloned into the BamHI site of pUC13 [Vieira J and Messing J (1982) Gene 19, 259—268] and propagated in a recA derivative of E_. coli JM83 JM83, A(recA-srlR) 306::Tnl0 [see Matfield, M (1983) Ph.D. thesis, University of Leicester].
DNA sequence analysis pAg3 DNA was sonicated, size-selected and shotgun cloned into the Sma I site of M13mpl9 [see Yanis-Perron C et al (1985) Gene 33, 103—119]. To determine the DNA sequence of the tandem-repetitive region of p^g3, 12 random clones were sequenced by the dideoxynucleotide chaintermination method [see Sanger, F et al (1977) Proc. Nat. Acad. Sci. USA 74, 5463-5467 and Biggin M D et al (1933) Proc. Natl. Acad. Sci. USA 80, 3963-3965]. 8 of these clones were derived from the tandem-repetitive minisatellite region of pAg3 and were used to define the consensus repeat sequence. M13 clones containing the 5' and 3' flanking regions were detected by hybridization with -^2P—labelled flanking probes a and b (see Fig. 1 described below) and sequenced to establish the flanking region sequence and the 9 beginning and end points of the minisatellite.
RESULTS Isolation of a specific mlnlsatellite from a DNA fingerprint Individual III9 from the Gujarati pedigree described by Jeffreys et al. [(1986) Am. J. Hum. Genet. 39, 11—24] is affected by HPFH (hereditary perslstance of foetal haemoglobin) and her DNA fingerprint, detected in Sau3A digest by mlnlsatellite probe 33.15, contains a 8.2 kb polymorphic fragment (fragment 'g'; Fig. IA) which tends to cosegregate with HPFH in other members of this pedigree as described in (1986) Am. J. Hum. Genet. 39, 11—24. This DNA fragment was purified away from other minisatellite fragments by two rounds of preparative gel electrophoresis (Fig. 1).
Fig 1 illustrates this purification by gel electrophoresis. DNA from individual III9 in the pedigree described by Jeffreys et al was digested with Sau3A and 6—9 kb fragments collected by preparative gel electrophoresis (fraction 1). These fragments were re-electrophoresed to give fractions 2-5. Aliquots of III9 DNA digested with Sau3A and of each fraction were electrophoresed through a 0.82 agarose gel and Southern blot hybridized with the mlnlsatellite probe 33.15. Fragment g (8.2 kb), which tends to cosegregate with HPFH, is approximately 1000-fold purified in fraction 3.
The fragment *g', detected in the Sau 3A digest referred to above, and purified as described to produce an approximately 1000 fold enriched fragment *g* fraction was cloned into>L47.1 as described in the above-mentioned Loenen and Brammar reference, and propagated on P2 lysogenic rec* E. coll to select for recombinant phage. The resulting library was screened by hybridisation to probe 33.15. The four positive plaques obtained were very samall (plaques <0.1 mm diameter) but could be replated at a low efficiency 0 0-8 pfu/plaque) on recB, recC E_. coll to produce normal-sized plaques (1mm diameter). Two clones, Agl and Ag3, were further characterised and shown to contain a Sau3A insert of 7.7 and 7.8 kb repectively. These clones were both derived from band g (see below), but were shorter than band g by 0.5 and 0.4 kb respecively. Since there was no size heterogeneity of the Sau3A insert in either Agl orAg3 grown on recB. recC E. coll (data not shown), we conclude that part of the insert has been lost from each clone during their initial propagation in rec+ E. coll.
Yields of Agl and Ag3 DNA prepared by the Blattner method [see (1977) Science 194, 161-169] were very low ( 1Z of the normal yields of AL47.1 recombinant DNA), again pointing to abnormal growth properties of these minisatellite clones. £he Sau3A Insert was therefore subcloned into pUC13 [see Vieira, J and Messing J (1982) Gene 19, 259—268] and propagated in a recA derivative of E. coll JM83 [see Matfield M (1983) Ph.D thesis University of Leicester] to minimise rearrangement of the insert. The resulting subclone, pig3 (see Pig. IB described below), contained a 7.1 kb Sau3A insert, 0.7 kb shorter than the insert in g3.
Organisation of mlnisatelllte fragment g The structure of the mlnisatelllte fragment in pAg3 was determined by restriction mapping (Fig. IB) and DNA sequencing (Fig. 2).
Fig. IB shows the organization of DNA fragment g. The Sau 3A insert in pAg3 was mapped with restriction endonuclease Alul (A), Ddel (D), Hae III (H) MboII (M), Pstl (P) and Sau3A (S). There are no cleavage sites for Hlnfl or Rsai. The 7.14 kb insert contains 171 tandem repeats of a 37 bp sequence (see Fig. 2) plus 747 bp flanking DNA. The 5' flanking region contains the beginning of an inverted Alu element (hatched). The origins of unique sequence flanking probes a and b are shown. 1 Fig 2 shows the DNA sequence of hypervariable fragment g. The sequence of the 5' and 3' flanking regions and the beginning and end of the minisatellite is shown together with the repeat sequences of three random regions (a—c) from the minisatellite. The beginning of the Inverted Alu element is shown in underlined uppercase, and several simple sequence regions in the 5’ flanking region are underlined. The consensus sequence (con) of the 37 bp minisatellite repeat unit is shown, and differences from this consensus are given for individual repeat units. The second repeat unit in region c contains a Haelll cleavage site (underlined), and this region therefore spans the internal Haelll site in the minisatellite (Fig. IB). The consensus repeat sequence is also shown aligned with the core sequence in a similar manner to that in Patent Specification No. .
The clone pjkg3 contains a 6.3 kb minisatellite devoid of restriction sites, except for a single internal Haelll site. The minisatellite is comprised of 171 repeats of a 37 bp unit which contains the sequence GTGGGCAGG; this sequence corresponds precisely to the most invariant part of the 11—16bp core sequence previously identified as being shared by several different human minisatellites (see Patent Specification No. and Fig 2 herein). The repeat units are not completely homogeneous; sequence analysis of several randomly—selected regions from within the mlnlsatelllte revealed a limited amount of repeat sequence variation. Most variants, including a 4 bp deletion which produces a subset of 33 bp repeat units, are diffused over more than one repeat unit. One variant (an A-bC transversion in region C) creates the unique Internal Haelll 2 site and is therefore probably only found in one repeat unit. The beginning and end repeat units of the minisatellite are noticeably more diverged in sequence than are internal repeats.
The minisatellite in p^g3 is flanked by nonrepeated DNA containing the normal density of restriction sites (Fig. IB). The beginning of the 5’ flanking region, is comprised of the head of an inverted Alu element. The remaining 5' and 3' flanking regions, defined by hybridization probes a and b (Fig IB), are unique sequence DNA and hybridize only to this locus in the total DNA (data not shown). The 5' flanking region contains a considerable amount of simple sequence DNA [polypurine and (ACC)n] (Fig 2).
Mlnlsatellite fragment R detects a single polymorphic locus To determine whether the entire cloned minisatellite fragment can be used as a hybridization probe to detect specifically the corresponding locus in human DNA, the Sau3A insert from p)kg3 was hybridized in the presence of human competitor DNA to human DNA digested with Hinfl. the restriction enzyme routinely used for DNA fingerprinting (Fig 3).
Figure 3 shows the Mendellan inheritance of polymorphic DNA fragments detected by pAg3. 8pg samples of human DNA were digested with Hinfl and electrophoresed through a 0.82 agarose gel. Digests were Southern blot hybridized with the Sau3A insert of ρΛ?3, in 1 x SSC at 65° in the presence of 62 polyethylene glycol and 50pg/ml alkalisheared human placental competitor DNA, and washed after 3 hybridization in 0.2 x SSC at 65°. p,\g3 detects a single locus vhich is heterozygous in all Individuals shown. Inheritance of alleles (indicated by letters) is Mendelian.
At high stringencies (0.2 x SSC, 65°), either one or two hybridizing fragments were detected in all individuals examined. pAg3 detected the 8.2 kb fragment g In previouslytested relatives of III 9, confirming that band g had been cloned (data not shown). At lower stringencies (1 x SSC, 65°), additional faintly hybridizing polymorphic DNA fragment were detected (data not shown).
DNA fragments detected by pAg3 at high stringencies segregate in a Mendelian fashion as alleles of a single locus (Fig 3). This locus is not sex-linked and also showed no significant but Incomplete sex-linkage in two large pedigrees studied (61 progeny tested, z 0.18 at $ 0.43; data not shown); it therefore behaves as an autosomal locus, and has been located on chromosome 7 (see Table 1).
Extreme polymorphic variation at this ainlsatelllte locus Hlnfl digests of DNA from 79 randomly-selected British Caucasians were screened with the insert from pag3, first singly and then in pools of 14 people (1 pg DNA per individual) which were electrophoresed though a 35 cm long 0.7Z agarose gel to maximise allele resolution. The lengths of the different alleles detected in this population sample are shown in Fig 4, together with the estimated number of repeat units in each allele and the allele frequencies. Thus Fig 4 shows the distribution of minisatellite allele sizes. The length of the minisatellite in the shortest common allele was determined by genomic mapping of this fragment in a homozygote, using flanking single-copy probes a and b (Fig 1) (data not shown). The number of repeats per allele is approximate and depends on the ratio of 37 to 33 bp repeat units in the mlnlsatellite. Excluding the short common 4 allele, the remaining alleles were sampled either once (42 alleles), twice (12 alleles), three times (12 alleles) or four times (5 alleles). This distribution does not differ significantly from that predicted if all of these alleles are uniformly rare (q0.0081, 2(4 d.f.] · 4.0), and is therefore consistent with a simple model of one common short allele (q=0.165) and 103 equally rare alleles (qx0.0081 per allele) being present in the population.
At least 77 different alleles could be resolved in this population sample, with repeat numbers ranging from 14 to^525 per allele. The homozygotes in the population sample were all homozygous for the shortest allele. The above estimates of number of alleles and the mean frequency of rare alleles are limited by gel resolution, and the true number of different length alleles in this sample may be greater.
The distribution of allele lengths does not appear to be completely random, but shows evidence of trimodality (Fig 4), with short (14-16 repeats), medium (41-68 repeats) and long (107—525 repeats) classes of alleles. A bimodal distribution of allele lengths has been previously noted in Caucasians for the hypervariable region located 5' to the human insulin gene (see Bell, G I et al (1982) Nature 295, 31—35], though this bimodality is not evident in blacks (Lebo, R V et al (1983) Proc. Nat. Acad. Sci. USA 80, 48044812].
The isolation of fragment g demonstrates that the large and highly polymorphic DNA fragments in DNA fingerprinting are in principle amenable to molecular cloning to provide locus—specific probes suitable for studying individual hypervariable regions. While fragment g could be cloned in bacteriophage A , the resulting clones showed abnormal growth properties on rec~*~ E. coli. This will lead to a depletion of mlnlsatellite clones from conventional amplified human libraries in phage. The cloned mlnlsatellite is unstable both in and on subcloning into pUC13 in recA E. coll; the final recombinant pAg3 had lost about 30 repeat units compared with fragment g. The physical map of pAg3 (Fig 1) does not therefore completely reflect the organization of fragment g.
The cloned DNA fragment has the structure expected for a minisatellite, establishing that fragment g is not derived from a longer satellite DNA. Despite the presence both of a core sequence in each repeat unit and part of an Alu sequence in the 5' flanking region, the cloned fragment g acts, in the presence of competitor human DNA, as a locusspecific probe. The failure of pAg3 to detect efficiently other core-containing minisatellites is due to the additional non-core DNA present in each repeat unit which probably interferes with cross—hybridization to other minisatellites (see Patent Specification No .
The cloned minisatellite shows extreme length polymorphism, presumably due to allelic variation both in the number of repeat units and in the ratio of 37 and 33 bp repeat types in each allele. In a random population sample of 158 chromosomes, one common and at least 76 rare alleles could be resolved. This locus is much more polymorphic than most or all of the cloned human hypervariable regions so far characterized including the selection of relatively short cloned minisatellites initially used to define the core sequence [see Patent Specification No. -9/^ ] . The heterozygosity at this locus is at least 96.6Z, with most homozygotes arising from the short common allele. 6 New alleles at this locus are generated by alteration in the repeat number, either by slippage during DNA replication or by unequal exchange driven by the core sequence, a putative recombination signal. Under the neutral mutation random drift hypothesis, the parameter 4Nev (Θ), where Ne is the effective population size and v is the mutation rate per gamete to a new length allele, can be most accurately estimated from the number of different alleles scored in a population sample, using the infinite allele model [see Ewens W J (1972) Theor. Popul. Biol. 3, 87-112].
We estimate Θ at 60-90 for this locus, depending on whether the common short allele is included or not. Since Ne for man isA/10^, the mutation rate v co new length alleles at this locus is approximately 0.002 per gamete. This value of v is an underestimate, since the number of alleles detected is limited by gel resolution and since there is not an infinite number of potential resolvable alleles. The average length of minisatellite DNA at this locus is 5kb, and thus the mutation (recombination) rate per kb minisatellite is >4 x 10 compared with per kb estimated for other shorter core-containing minisatellites and a mean meiotic recombination rate of 10"5 per kb for human DNA [see Jeffreys, A J et al (1985) Nature 314, 67—73]. Thus the rate of generation of new alles at this mlnlsatelllte locus is remarkably high, consistent with the Inventor's previous suggestions that these core-rich regions may be recombination hotspots. Presumably, the mutation rate is relatively low for short alleles, which might explain how the shortest allele has drifted to achieve a significant frequency in the population without being disrupted by unequal exchange during this process.
DNA fingerprints have proved a powerful method for individual identification and for establishing family relationships in for example paternity and immigration disputes. The accuracy of this method is determined by the low mean probability x that a band is shared by two randomly—selected individuals. For British Caucasians, x has been estimated empirically at 0.2 for DNA fingerprint Hincl fragments larger than 4 kb. In cases where band sharing between individuals occurs (that is, where a band in one Individual is matched in a second individual by a band of similar mobility and autoradiographic intensity), it is not clear whether the shared bands represent identical alleles of the same minisatellite locus. The allele distribution in Fig 4 enables us to calculate x for alleles >4 kb; for this specific mlnisatelllte locus, x " 0.016, an order of magnitude lower than the estimate from multi—locus DNA fingerprints. If this cloned minisatellite is typical of loci represented in DNA fingerprints, then most bands shared between unrelated DNA fingerprints are due to fortuitous comigration of different mlnisatelllte fragments. The important practical consequence of this is that, in cases of non-exclusion in for example paternity disputes where all paternal bands in a child are precisely present in the DNA fingerprint of the putative father, the very low probability of false Inclusion previously calculated for x · 0.2 ls a gross overestimate of the true probability (for x 0.016).
Using DNA fingerprint probes 33.6 and 33.15, it is possible to score the segratlon of up to 34 dispersed autosomal loci In large human sibships. For most loci examined, only one of the two alleles is scorable in the set of larger (>4 kb) resolved DNA fingerprint fragments, suggesting that large size differences exist between 8 mlnlsatelllte alleles, with many alleles being located In the poorly resolved (<4 kb) region of the DMA fingerprint. This is also seen for the cloned minisatellitej Hinfl alleles at this locus vary from 1.7 to 20.4 kb in length, and the allele frequency distribution in Fig 4 shows that both alleles of this locus would be resolved in the DNA fingerprints of only 402 of individuals, while neither allele would be scorable in 142 of people.
Minisatellite probes 33.6 and 33.15 detect together about 60 hypervariable loci, many of which should now be amenable to cloning to provide a bank of highly informative single locus probes, for example ideal for linkage studies in man. Linkage analysis of inherited disorders is also possible in single large families using the entire DNA fingerprint. If a polymorphic fragment is detected which appears to cosegregate with the disease, it is essential that this fragment be cloned to provide a locus-specific probe for extending the linkage analysis to additional affected families.
In the following Example 2 below the materials and methods set out below were used. a) Cloning a selection of large mlnlsatellites pg blood DNA from each of 40 randomly—selected individuals were pooled, digested to completion with Sau3A and 5-15 kb fragments isolated by preparative electrophoresis in a 0.62 agarose gel followed by electroi 9 elution onto a dialysis membrane. The purified fraction vas electrophoresed in a second preparative gel to remove all traces of contaminating small Sau3A fragments. 50 ng of the 5—15 kb fraction were ligated to 100 ng /1.47.1 arms isolated after cleavage with BamHI [Loenen and Brammar, (1980) Gene . 249—259] packaged in vitro and a library constructed, screened with human minisatellite probes 33.6 and 33.15 (see Patent Specification No. ) and positive plaques Isolated as described in Example 1 to produce the MS series of recombinant phage. b) Isolation of alnisatelllte hybridization probes Recombinant phage DNA was digested with Sau3A and the large insert fragment separated from small vector fragments by electrophoresis in low gelling temperature agarose (Sea Plaque). The gel slice containing the insert was dissolved in 3 vol water at 65° and aliquots containing 10 ng insert DNA were labelled with 32p by random oligonucleotide priming [Feinberg and Vogelstein, (1984) Anal. Biochem. 137, 266—267. c) Southern blot hybridization Genomic DNA samples were restricted and electrophoresed as described by Jeffreys et al (1986) Am. J. Hum. Genet. 39, 11-24. DNA was transferred to Hybond-N (Amersham), fixed by u/v irradiation and prehybridized at 65° for 5 min in 0.5M sodium phosphate, 7Z SDS, ImM EDTA (pH7.2) [Church and Gilbert, (1984), Proc. Natl. Acad. Sci. USA 81, 1991—1995. Filters were hybridized overnight with 0.5 pg/ml 32P-labelled probe DNA (specified activity ^10^ cpmZug DNA) in the presence of 25 μg/ml sheared singlestranded human placental DNA competitor. After 0 hybridization, filters were washed at 65° in 40 mM sodium phosphate, IS SDS (pH7.2) followed by a high stringency wash at 65° in 0.1 x SSC (15 mM NaCl, 1.5 mM trisodium citrate pH7.0) 0.012 SDS. Filters were autoradiographed from 3 hr co 1 week at —80° in the presence of an intensifier screen, d) Determination of the tandem repeat sequence of the MS recombinants Each MS recombinant DNA was sonicated and 0.3 — 0.6 kb fragments size-selected and shotgun cloned into the Smal site of M13mpl9 [Yanis-Perron, Vieira and Messing, (1985), Gene 33, 103—119]. Recombinant phage were screened by plaque hybridization with 32p-iat>eiie(j hs insert DNA. 10 strongly-positive single-stranded phage DNAs from a given MS recombinant were compared pairwise by the C—test [Winter and Fields, (1980) Nucleic Acids Res. 8_, 1965—1974]; most DNAs fell into two complementary C-test groups and were therefore likely to be derived from the long, tandem-repetitive region of the AMS Insert. Two M13 recombinants from each of the two complementary groups were sequenced by the dideoxynucleotide chain-termination method [Sanger, Nicklen and Coulson, (1977) Proc. Natl. Acad. Sci. USA 74, 5463—5467; Biggin, Gibson and Hong, (1983) Proc. Natl. Acad. Sci. USA 80, 3963-3965] to determine the consensus repeat sequence of each MS recombinant on both strands.
Example 2 a) Isolation of a selection of locus-specific hypervariable DNA probes The strategy for cloning a selected fragment from a human DNA fingerprint by preparative gel electrophoretic isolation of the fragment followed by cloning in bacteriophage has been described in Example 1. To isolate a wider range of minisatellites, 6—15 kb size-selected Sau3A 1 fragments from DNA pooled from 40 randomly—selected individuals were cloned into the BamHI replacement vector AL47.1 [Leonen and Brammar, (1980)? "A bacteriophage lambda vector for cloning large DNA fragments made with several restriction enzymes" Gene 20, 249-259). Since human mlnisatellltes can show substantial allelic variation in length, as demonstrated in Example 1, the use of pooled human DNAs to clone large Sau3A fragments should maximize the number of clonable hypervariable loci which have large Sau3A alleles. From a library of 2000 recombinants, 5 phage were isolated by hybridization to human mlnisatelllte probe 33.15 and an additional 5 phage were detected by probe 33.6, to produce the MS series of recombinants (see Table 1).

Four of the recombinants detected by probe 33.6 (AMS8, 40, 42 and 47) hybridized to the same pattern of variable DNA fragments and are therefore derived from the same hypervariable locus (Fig 5 Table 1).
Figure 5 shows an Example of the screening of A MS recombinants for locus—specific hypervariable DNA probes. pg samples of DNA from three unrelated individuals were digested with Hinfl. eletrophoresed through a 0.32 agarose gel and Southern blot hybridized with 32p_iabelled Sau3A inserts from pAg3 (Example 1),AMS3 andAMS40 as herein described in Materials and Methods. Filters were washed after hybridization in 0.1 x SSC at 65°, and autoradiographed in the presence of an intensifier screen for 1 day (left panel) or 1 week (right panel). Note that»\MS8 andAMS40 detect the same hypervariable locus, and that on prolonged autoradiography, additional variable DNA fragments are detectable.
The remaining recombinants A MSI, 31, 32 and 43 were derived from different loci which did not Include the previously characterised pAg3 locus (see Example 1 and Fig 5). Although none of these A MS recombinants produced DNA 'fingerprints' of multiple variable fragments, most AMS probes were seen to cross—hybridize weakly to additional polymorphic DNA fragments on prolonged autoradiographic exposure (Fig. 5). 4 Two of the Λ MS recombinants detected by probe 33.15,A MS3 andAMS30, failed to detect a specific locus in human DNA digested with Hinfl or Sau3A, either in the presence or absence of human competitor DNA. On prolonged autoradiograph, both recombinants detected the same faint pattern of variable DNA fragments (data not shown). We have no explanation for this lack of locus—specificity, and these two MS recombinants have not been further characterized.
Thus despite previously reported difficulties in cloning large and unstable human minlsatellltes [see for example Nicholls et al (1985) Nucleic Acids Res. 13, 7569— 7573 and Wyman et al (1980) Proc. Natl. Acad. Sci. USA TJ_, 6754-6758] we have been able to demonstrate that at least some of the largest and most variable DNA fragments detected in a DNA fingerprint are amenable to cloning in bacteriophage A, provided that the Inserts are stabilised by propagation of phage in a recBC E,. coll host. b) Determination of the repeat sequence units of cloned mini—satellites Random segments of insert DNA from each Λ MS recombinant were sequenced to determine whether each cloned hypervariable locus consisted of tandem-repetitive minisatellite (see Materials and Methods). All A MS clones were shown to consist primarily of tandem repeat units ranging in length from 9 bp forAMSl to 45 bp forAMS43 (Pig 6).
Fig 6 shows the consensus repeat sequence units of the A MS series of minlsatellltes. Random segments of each cloned mlnlsatelllte were sequenced to define the consensus repeat unit. Variable positions in each consensus are shown as: R, r = A or G; Y, y C or Tj N, n · any base. The minisatellite in MS8 consists of two mutually—interspersed repeat units 29 and 30 bp long. The consensus repeat sequence of pAg3 is also shown in Fig 2. Each repeat sequence is aligned with the core sequence, with matches shown in uppercase, and a new core sequence derived from a comparison of the core with pAg3,AMS31 and XMS32 is also disclosed.
In no minisatellite are the repeat units completely homogeneous, consistent with the variation between repeat units seen at previously sequenced minisatellites (see Patent Specification No. and Example 1 . herein). Most notably, the mlnisatelllte inAMS8 consists of an intermingled array of two closely—related but distinct repeat units 29 and 30 bp long (Fig 6). The end-points of the minisatellites in the A MS recombinants have not yet been determined.
Thus five new hypervariable loci have been Isolated, each consisting mainly of a tandem-repetitive minisatellite. The tandei»-repeat units of pAg3, AMS1.AMS31 and>MS32 each contain the core sequence, as expected (Fig 6). However, the copies of the core sequence are imperfect, and comparisons of the repeat units of these minisatellites do not clearly define a new core sequence preferentially associated with these large and extremely variable loci. It seems likely instead that a wide range of core derivatives may be associated with large mlnisatellltes. More notably, mlnisatellltes AMS3 andAMS43 detected by probe 33.6, which consists of tandem repeats of a diverged version of the core sequence (see Patent Specification No. s.a'Q/SS' ) , contain highly diverged versions of the core sequence (Fig 2). Again, comparisons of A MS8, A.MS43 and 33.6 do not clearly reveal a new specific sequence preferentially associated with these three loci (data not shown). It is clear that a detailed search for further sequence motifs associated with the most variable minisatellites, particularly those detected by probe 33.6, will require the analysis of a much larger spectrum of cloned mlnlsatellites. c) Mendellan Inheritance and variability of loci detected by clones mlnlsatellites The five new mlnlsatellites isolated,Λ MSI, 8, 31, 32 and 43, each detect a single large and variable locus. Mendellan inheritance of all loci has been confirmed by analysing segregation in large horizontal pedigrees provided by the CEPH programme (Fig 7).
Figure 7 shows the Mendellan inheritance of the hypervariable locus detected byAMS32. 1 pg DNA samples from CEPH family 1413 were digested with Alu I and Southern blot hybridised to the 32p—labelled Sau 3A insert fromAMS31.
This family is completely informative at this locus.
The extent of allelic variability for each probe has been estimated by analysing the frequency of allele sharing between randomly—selected English individuals (Fig 3). Figure 3 provides an estimation of allelic variability at the hypervariable locus deteced by MS43. 1 pg samples of DNA from twenty random-selected English people were digested with Hinfl and Southern blot hybridized toAMS43. All individuals are heterozygous, indicating that the level of heterozygosity at this hypervariable locus is high (H > 0.86, p > 0.95). A more accurate estimate of heterozygosity may be made by comparing alleles in each individual with alleles in the six nearest neighbours on the autoradiograph to estimate the levels of allele sharing between individuals.
For example, the larger allele in individual 5 appears to be present in 7, but not in 2, 3, 4, 6 and 8. Similarly, the smaller allele in 5 is not present in 2—4 or 6—8. Over all individuals examined, s * 0.11, from which the mean allele frequence q can be estimated as q · 1 — (1—s)^ 0.056 and the heterozygosity as (1-q) 942. This is a minimum estimate of heterozygosity limited by gel electrophoretic resolution.
All loci are highly variable with heterozygosities ranging from 902 forAMS8 to 992 forAMS31 (see Table 1 above). The extent of allelic length variation has been further analysed by comparing the spectrum of alleles resolved in pools of 15 and 150 individuals (Fig 9). Figure 9 shows an analysis of allelic length variation at hypervariable loci in pools of human DNA. 10 pg samples of DNA from a single individual (a), from a pool of 15 individuals (b) and from a pool of 150 people (c) were digested with Alul (forAMS32) or Hinfl (for all remaining probes) and Southern blot hybridized with the Indicated locus—specific hypervariable probes. All individuals were randomly-selected North Europeans. Individual a was included within pool b, and all pool b individuals were Included in pool c. It should be noted thatAMS43 detects a second variable region represented by the short Hinfl alleles marked 0; this region has not been further characterised.
For the least variable locus,AMS8, there are two predominant alleles 5.3 and 7.2 kb long plus 7 lower frequency alleles resolvable in the pool of 15 people. That the two predominant alleles are not the result of sampling error in these 15 individuals is shown by their similar prevalence in the pool of 150 individuals, together with a larger spectrum of low frequency alleles. Similarly,Λ MS43 (942 heterozygosity) shows 7 major alleles shared by the 15— and 150-lndivldual pools, together with many minor alleles.
In contrast, the most variable loci AMS1, 31 and 32 and pAg3, with heterozygosities estimated at 97—992, show no alleles with a significant population frequency which are shared at equal Intensity by both pools of individuals (with the exception of the shortest 1.6 kb allele of pAg3 as described hereinbefore, and thus the number of alleles at these loci is likely to be very high. For example, at least 50 different A MS32 alleles can be resolved in the pool of 150 individuals; this will be a minimal estimate of the total number of alleles limited by gel electrophoretic resolution.
The length dispersal of alleles in Caucasians also varies between these hypervariable loci (see Fig 9 and Table 1), Most alleles ofAMS31 are distributed fairly uniformly over a relatively narrow size range of 5.5 — 9.3 kb, whereas alleles of A MSI vary in size from 2—20 kb. There is evidence in some cases of non-uniformity of allele length distribution; in partlcularA MSA3 shows two predominant allelic size classes of 5—6 kb and 8—14 kb, and pAg3 shows three size classes of 1.6—1.7, 2.8-3.6 and 5—15 kb as hereinbefore described in Example 1.
As indicated above the loci detected are extremely variable and Indeed are amongst tbe most polymorphic loci so far isolated from human DNA. d) Chromosome assignment of hypervariable loci None of the hypervariable locus—specific probes hybridise to rodent DNA, and therefore the segregation of these loci could be followed in man-rodent somatic cell hybrids [see Fig 10 and Table 2 below]. The six loci were assigned to four different autosomes, with chromosomes 1 and 7 each bearing two hypervariable loci.
Figure 10 shows the segregation of the hypervariable locus detected byAMS32 in a panel of humanrodent somatic cell hybrid DNAs digested with Alul. This locus cosegregates with human chromosome 1 (see Table 2 below). Interestingly, the hybrid cell line MOG 2C2 carried two 9 alleles of bothAMS32 and AMSl (data not shown). This strongly suggests that both parental copies of human chromosome 1 have been retained in this hybrid, and, since all other positive hybrids contained only a single allele at each of these loci, this provides strong supporting evidence for synteny of A MSI and AmS32. Hybrid F4SC13cll2 contains chromosome lp but is negative forAMS32; thus A MS32 is provisionally localised to chromosome lq.

The deduced chromosome assignment of each locus—specific hypervariable probe is given, together with the fraction of unamblgously informative cell hybrids which are concordant for the presence or absence of the Intact chromosome and the hypervariable locus. For each hypervariable probe, all chromosomes except one were multiply excluded by this analysis.
The hybridization of > MSI to hybrid 8 (F4SC13cll2) containing chromosome lp suggests thatAMSl is located on lp. Conversely,Λ MS32 does not hybridize to hybrid 8, suggesting localization to lq. pAg3 does not hybridize to hybrid 2 (FIR5) which contains chromosome 7pter*q22. Furthermore, hybrids JDA 13.1 and JDA 3 containing 7pter-»q31.3 and 7q31.3->qter respectively are negative and positive respectively for pAg3 (data not shown), localizing pAg3 to 7q31.3-*qter. Conversely, Λ MS31 hybridizes to FIRS and JDA 13.1 but not JDA 3, suggesting a localization to 7pter-*q22. This lack of clustering was confirmed by linkage analysis in large CEPH sibships, which showed no significant linkage between either pair of syntenic markers (z> —2 at >0.35 for each pair, data not shown).
All six cloned minisatellite loci, including pAg3 described in Example 1, are autosomal and dispersed; of the two syntenic pairs of minisatellites found, neither show significant pair-wise linkage. This autosomal localization and lack of clustering is fully consistent with previous results from segregation analysis of DNA fingerprints which showed that the numerous hypervariable DNA fragments detected by polycore probes are derived from multiple and dispersed autosomal loci, although the chromosome localization of individual fragments could not be deduced from DNA fingerprints.
The cloned minisatellites so far localized tend to be derived from the larger human autosomes (Table 1), as expected if they are dispersed randomly over the human genome. In the absence of precise regional localization, it remains possible that these mlnisatellltes are preferentially located at centromeres and telomeres, which are rich in simple sequence satellite DNA. However, segregation analysis of DNA fingerprint fragments in recombinant inbred strains of mice has shown that murine minisatellites are not preferentially associated with centromeres or telomeres, and it is likely that their human counterparts are similarly dispersed.
Example 3 Mlnisatelllte probe sensitivity and forensic applications The tandem repetitive minisatellite probes which have been tested are very sensitive, presumably as a result of the repetitive nature of both the hybridization probe and the target· minisatellite DNA. The Southern blot autoradiographic signal obtained after overnight hybridization is saturated at probe DNA concentrations of >0.1 ng/ml (data not shown), and signals can be readily obtained from 60 ng or less of human genomic DNA (see Fig llA). Similarly, depending on the genotypes of the individuals tested, these probes can detect an admixture of 2% or less of one individual's DNA with another (see Fig 11B).
The sensitivity and variability of these locusspecific mlnlsatellite probes makes them particularly useful in forensic medicine. Fig 11C shows an analysis of semen stains from two victims who had been sexually assaulted and murdered, where the recovery of DNA from the second victim was insufficient for conventional DNA fingerprint analysis which requires at least 0.5 pg DNA per test (see Patent Specification No . -3e,) Thus Figure 11 shows an assessment of the sensitivity of locus specific probes and their application to the forensic analysis of a double rape/murder case. In Figure llA decreasing amounts of human DNA digested with Hinfl were Southern blot hybridized with 32p-labelled insert DNA from MSI. Filters were autoradiographed in the presence of an intensifier screen for 1 week. In Figure 11B decreasing amounts of individual A DNA were mixed with 4 pg individual B DNA in the Indicated ratios, and Southern blot hybridized, with Λ MSI as in Fig llA. In Figure 11C victims X and Y had been sexually assaulted and murdered. A suspect Z had been charged with the murder of Y, and forensic evidence further suggested that both X and Y had been murdered by the same individual. DNA from the following forensic specimens was isolated and analysed; a, hair from X taken two days post—mortem; b, a mixture of semen and vaginal fluid recovered from the pubic hair of X; c, fresh blood from suspect Z; d, cardiac blood taken one day post-mortem from Y; e, vaginal swab from Y bearing semen, blood and vaginal material; F, a stain from Y's skirt bearing semen and blood. Samples a and b had been stored dry at 4° for 3 years, samples d and e at 4° for 2 months and sample f stored dry at 4° for 2 months. DNA was extracted following the procedures of Gill, Jeffreys and Werrett (1985) Nature 318, 577-579, digested with Hlnfl and Southern blot hybridized to 32p_ labelled A MSI insert. 0.8 pg DNA was analysed in each sample, except for sample e (0.1 pg DNA) and f (0.04 pg DNA). Autoradiography was for one week in the presence of an intensifier screen. Note that the semen stains b, e and f each contain two hybridizing DNA fragments which are not attributable to the victim. In addition, sample b contains the victim's alleles derived from vaginal DNA. The semen alleles in b, e and f are indistinguishable, suggesting that victims X and Y had indeed been sexually assaulted by the same man. The alleles of suspect Z do not match those of the semen stains.
These results were confirmed by hybridization with AMS31 (data not shown) and by DNA fingerprint analysis of larger amounts of forensic material. In the light of this evidence, the charges preferred against the suspect were discontinued by the crown prosecutor.
Example 4 Pooled mlnisatelllte probes The sensitivity of these minisatellites in Southern blot hybridizations permits pools of probes to be used to detect variable DNA fragments from several loci' simultaneously, as shown for a pool of 5 probes (pAg3, AMS1, AmS8, AMS31 and AMS43) in Fig 10. In theory, the number of ^ different DNA fragments detectable by 5 probes is ^1 + Hi), where Hf is the heterozygosity of the i th probe. For these 5 probes, on average 9.78 fragments should be detected per individual. In practice, 8.4 * 1.2 (S.D.) bands > 2 kb are resolved (40 randomly selected individuals tested). This loss of resolvable bands is partly due to exclusion of the small (1.6 kb) and relatively common pAg3 allele (Example 1, mean loss per individual · 0.33 band), but is mainly the result of electrophoretic comigration of different minisatellite alleles.
The multilocus Southern blot patterns are highly individual-specific with only 182 (S.D. ♦ 112) of DNA fragments shared between pairs of randomly—selected North Europeans (40 pairs tested). For sibs, the level of fragment sharing rises as expected to —572 (10 sib pairs tested).
In father/mother/child trios, all offspring fragments can be traced back to the parents (Fig 12). Each offspring contains 3.4 ♦ 0.5 (S.D.) DNA fragments which are specifically of paternal origin, and an equal number of maternal—specific DNA fragments (10 father/mother/child trios tested).
Thus as indicated above, Figure 12 shows the detection of multiple hypervariable loci in human DMA by hybridisation with pooled mlnlsatellite probes. 4 pg DNA samples from a random selection of English people (1—6), from sib pairs (7, 8 and 9, 10) and from father/child/mother family groups (11, 12, 13 and 14, 15, 16) were digested with Hinfl and electrophoresed though a 0.82 agarose gel until all 5δ fragments less than 2 kb had electrophoresed off the gel.
The digests were Southern blot hybridized with 2 ng of insert DNA from each pAg3, AMS1, AMS8, AMS31 and AMS43j inserts were pooled prior to labelling with 32p by random oligonucleotide priming. Variations in band labelling intensity presumably arise from variability in the efficiency of labelling and hybridization of individual probes. 7 CERTIFIED CELL LINES - CCL The L-M(TK') subline is potentially useful in a variety of genetic and biochemical studies, including somatic cell hybridization (Proc.

ATCC CCL 2_HtLa_(Eplfheloid carcinoma, cervix, Human)_ HeLa was the first aneuploid. epitheliaHike cell line to be derived from human tissue and maintained continuously by serial cell culture. It was isolated by G.O. Gey, W.D. Coffman, and M.T. Kubicek in February, 1951, from a carcinoma of the cervix of a 31 year-old Negro female (Cancer Res. !2:264.1952). In a recent re-examination of the original slides Jones tt at. (Obstet. Gynecol. 38: 945-949. 1971) diagnosed the tumor as an adenocarcinoma. Since its origin, it has been one of the most widely studied cell lines.

In 1954. the line was frozen (Proc. Soc. Exp. Biol. Med. 87: 480, 1954). and stored until 1959, at which time it was recultured and refrozen until I960. After another recultivation and freezing, it was reactivated in November, 1961. for the American Type Culture Collection.

Sandberg (Cancer 17:170. 1964) from the pfeurai effusion of a patient with an extensive malignant tumor of the nasal septum. The tumor was diagnosed as an anaplastic squamous cell carcinoma. The cells were originally grown in RPM] medium 906K and 2-5% fetal calf serum, but also grew well in other culture media. The cell line was grown on glass by Moore and Sandberg for 35 transplants apparently without alteration of the normal karyotype, however Moorhead re-analyzed the karyotype of the RPMI 2650 cells (Exp.

ATCC CCL 32_MB III (de Bruyn-Gey)_(Lymphosarcoma, Mouse) _ Strain MB III was derived in 1947. by W.M.deBruynandG.O. Gey. (Acta Unio Internationale contra Cancnim 7.-772.1952) as one of three cell strains (MB I. II. and ill) with tumor-producing and non-tumor-producing properties initiated from a mouse lymphosarcoma MB (T86I57) which originated in 1935. as a spontaneous tumor that arose in a Fl hybrid of the dilute brown Murray-Little strain and C57 black strain. The primary strain, MB I, consisted of a mixed population of lymphoblasts and fibroblasts and is tumor-producing. Strain MB III was derived from a culture of MB I. in which the fibroblasts gradually disappeared and the round lymphoblastic cells became predominant. Concurrent with the disappearance of the fibroblasts, the tumor producing capacities of the strain were lost.
The original stock of MB 111 cells was cultivated in 66% human placental cord serum, 16% bovine embryo extract and 18%GeyY BSS containing 100 units of penicillin per ml. The medium was later altered to 50% human placental cord serum. 10% bovine embryo extract and 40% Gey's BSS. The MB 111 cells have been readily adapted to a wide variety of the media (Eagle's. Waymouth's etc.) supplemented with serum. In contrast to the early Μ B strains the Μ Β II1 cells grow readily in suspension systems. They were the first cells to be grown in suspension.
Strain MB Ill has been employed in studies relating to: (I) tumorigenicity. (2) suspension culture systems. (3) chromosome constitution. (4) cell nutrition and (5) rickettsia.
A roller tube of MB III grown on Eagle's MEM * 30% calf serum was submitted to the American Type Culture Collection in March. 1965. The medium was altered to Eagle's MEM. with non-essential amino acids and sodium pyruvate in Earle's BSS plus 10% newborn calf serum and the cells were adapted to static cultures for characterization (Cancer Res. 9:282.1949; ibid.. 9:395.1949.

Owens, on December 31.1964. from minced ear epidermis of an adult male cottontail rabbit which had papillomatosis. The cells were initiated in minimum essential medium (Eagle) with non-essential amino acids, and Earle's BSS with reduced bicarbonate (0.85 g per L). 80%: newborn bovine serum. 20%; penicillin (250 u/ml): streptomycin (0.1 mg/L). polymyxin (50 u/ml); fungizone (0.03 mg ml). All antibiotics were omitted starting with the 3rd passage. The serum concentration was reduced to 10% (passage 2 to 66) and fetal bovine serum was utilized from passage 31 to 66. This line has been cultured continuously at pH 7.4-7.6 and 37 C. but can be adequately maintained at 25 C. Cell morphology varied from fibroblast-like to epithelial-like in early passages. A gradual loss of fibroblast-like cells has resulted in the stabilization of fairly uniform epithelial-like cells, which tend to become spindle-shaped when crowded.
The cell line was developed especially for studies of epidermis specific virus replication (Shope Papilloma. Rabbit) and may be useful in studies of viruses producing lesions in the skin. The reference seed stock was frozen on April 21. 1967. at the 66th serial passage. It has been demonstrated that the cells can be successfully propagated for at least 20 passages beyond the frozen reference seed stock.

Owens, on November 6. 1964. from trypsinized uterine tissue of an adult female raccoon. The cells have been grown continuously in minimum essential medium (Eagle) with non-essential amino acids, and Earle's BSS with reduced bicarbonate (0.85 g per L). 90%; fetal bovine serum. 10%; antibiotic-free; pH 7.4-7.6. Early passages consisted of cells which were predominantly epithelial-like. Patches of small close knit fibroblast-like cells were noticed at passage 10 and were successfully separated from the remainder of the cell population by partial trypsinization. The small fibroblast-like cells were carried as the main line and icached a proliferation peak at the 15th passage. Beyond this passage the growth rate has been slower.
This cell line was developed for studies of feline and canine viruses since the raccoon is one of the few known animals which is susceptible to both of these groups of viruses. The reference seed stock was frozen on February 16. 1967. at the 65th serial passage. It has been demonstrated that the cells can be successfully propagated for at least 20 passages beyond the frozen reference seed stock; however the rate of growth is very slow.

ATCC CCL 75_WI-38_ (Lung, diploid. Human)__ The W|-38 human diploid cell line was derived by L. Hayflick from normal embryonic (3 month gestation) lung tissue of a Caucasian female. The growth medium used was Eagle’s medium in Earle's balanced salt solution supplemented with 10% calf serum < Exp. Cell Res. 25: 585. 1961). The medium should be prewarmed to 37 C before use. The pH should be brought to 7.2 before addition of the serum. The final pH of the medium must be less than 7.4. WI-38 cells have a finite lifetime of 50 plus or minus 10 population doublings with a doubling time of 24 hours (Exp. Cell Res. 37:614. 1965). It has been shown to have one of the broadest human virus spectra of any cell population that has been tested and is especially useful for isolation of rhinoviruses. The cells are free of contaminating viruses, mycoplasma* or any other microorganism and do not form turnon when inoculated into the cheek pouch or subcutaneously into terminal human cancer patients. It has a diploid karyotype except at the very late passages. The cells do not grow •n suspension but form a multilayered membrane when held for long periods at 37 C with intermittent pH adjustments. WI-38 fibroblasts produce collagen and have been used for the preparation of a number of human virus vaccines (Am. J. Hyg. 73:240,1962; First International Conference on Vaccines Against Viral and Rickettsial Diseases of Man, Pan American Health Organization. Publication No. 147: 581. May. 1967).

Cut, Fete catus)__ CRFK cells were initialed from the conical portion of the kidneys of a 10-12 week-old normal female domestic cat in June of 1964 Primary cultures were prepared by trypsin digestion and grown in Hanks' BSS supplemented with essential amino acids, vitamins.
L-glutamine and 10% calf serum plus antibiotics. Since the I46th passage the cells have been cultivated on MEM with 0.5r, lactalbumin hydrolysate with Earle's BSS and 10% fetal bovine serum. The line was contaminated with mycoplasma and was treated with tetracyclines (R. A. Crandel) et a!.. In Vitro 9: 176-185. 1973). CRFK has been extensively employed in feline virus research (J. Am. Vet. Med. Assoc. /58/976-980. 1971: J. Nat. Cancer Inst. 4//55-60. 1972). The cell line has been shown to be susceptible to six herpes viruses and eight feline picornaviruses with demostrable cytopathic effects.
An ampule of CRFK cells was originally submitted to the ATCC at the 166th passage by W.A. Nelson-Rees in May. 1975. Following deposition it was ascertained that the CRFK line was infected with bovine viral diarrhea virus(BVD). In subsequent years various stocks of CRFK obtained from various laboratories were tested by R.A. Van Deusen at the National Veterinary Services Laboratories (N VSL). USDA in Ames. Iowa in hopesof finding a source of BVD-free CRFK cells. In 1984 Dr. VanDeusen informed the ATCC that a BVD-free culture of CRFK cells had been found. The cells were received at NVSL in March. 1983 at passage 165 as a frozen ampule which had been prepared in February' 1976 at the Naval Biosciences Laboratory. Oakland. California. Extensive testing by the NVSL found no evidence of any viral contamination in the CRFK cells from this frozen ampule. Seed stock prepared from this material was submitted to the ATCC by R.A.

ATCC CCL 95.1 Wl-26 VA4_ (Lung, Human) SV40 virus-transformed_ The WI-26 VA4cell line was derived by A.J. Girardi. F.C. Jensen and H. Koprowski in December, 1963 (J. Cell. Comp. Physiol. 65: 69-84.1965). The cell line is a SV40 virus-transformed derivative of Wl-26 cells, a human diploid cell line established from embryonic lung tissue of a male Caucasian (Exp. Cell Res. 25/585-621.1961: ibid.. 37: 614-636.1965). The Wl-26 cells, cultured in Eagle's basal medium (BME) with twice the concentration of amino acids and vitamins with Earle's BSS and 10% fetal bovine serum, were exposed to SV40 virus in phase III of their in vitro life span.
Cytopathicand proliferative changes collectively termed "transformation(J. Nat. Cancer Inst. 32:917-937,1964) were first noted 2-4 weeks after exposure to virus. In the initial stage of transformation 10 to 20% of the cells in the culture underwent lysis. The second stage of transformation was marked by a rapid proliferation of most of the remaining cells. The proliferation stage lasted for 9 weeks before the onset of the third of "crisis stage. The crisis stage was characterized by a massive degeneration of the culture and was accompanied by abnormal cell division, the appearance of giant and multinucleated cells, and a progressive decline in cell proliferation. After 5 months a few cells recovered, proliferated rapidly, and were designated as the Wl-26 VA4 cell line. The cells contain both SV40 neo (T) antigen and SV40 transplantation antigen, but infectious virus has not been rescued by any means including cell fusion. The cell line, which has been subcultured for more than 200 passages, was submitted to the American Type Culture Collection in the 145th passage.

ATCC CCL 114 RPMI 1666_(Normal lymphoblasts, Human)_ RPMI 7666 is one of a large series of apparently permanent cells lines derived by G E. Moore from leukocytes in the peripheral blood of donors with and without malignancies. This cell line was initiated from the leukocytes obtained from a 32 year-old. Caucasian male having no known malignancy (G.E. Moore, et al.. J.A.M.A. 199: 519. 1967). Cells m culture are lymphoblasts and grow in suspension in stationary or spinner cultures. Growth is characterized by the formation of large clusters of cells that are suspended :n the medium. Epstein-Barr virus particles are found in the cells by thin section electron microscopy, and it has been suggested (see above reference) that this agent may promote differentiation of the lymphocytes, resulting in multiplication. These cells also produce mmunoglobulin in vitro (see above reference).

Detroit 532). The line was derived by W.F. Simpson in October of 1966 from a skin biopsy of a Caucasian female infant exhibiting anomalies associaied with D trisomy syndrome (W.W. Zuelzer, et al.. J. Pediatrics 72. 367,1968). Karyologic analysis showed that 94% of the cell population is46.XX.C«.D-. The appearance of the extra C chromosome is compatible with a translocated D on a partial extra D as shown in blood and marrow specimens. A small (2%) population of fibroblast cells is present having 3 extra D-D translocated chromosomes (chromosome number = 48). The karyoty pe is stable for J2 or more transfers beyond the frozen seed stock when cells are transferred at an inoculum of 2 x JO* cells ml. However, it was found cells having 48 chromosomes multiply at a faster rate than the 46 chromosome cells. W'hen the cells are transferred at twice the above inoculum, it was found that the percentage of cells having 48 chromosomes increased rapidly from 2% to about 25% of the cell population in 5 transfers, and 40% bv transfer 10.

The cells were cultured on minimum essential medium (Eagle) with nonessential amino acids in Earle s BSS supplemented with 10% inactivated fetal bovine serum and antibiotics. Subcultivation was carried out in such a way so as to eliminate the growth of fibroblasts and favor the proliferation of epithelial cells. Once established, the epithelial-like ceils proliferated rapidly with loss of contact inhibition, exhibited a doubling time of 26 hours, and reached saturation densities of 1-2 x 10* cells/cm2. Chromosome analysis on the HT-1080 cell line revealed a stemline number of 46. Pseudodiploidy and the presence of marker chromosomes was noted, however. Tumors developed in all subcutaneously inoculated NIH Swiss mice immunosuppresscd with anti-thymocytic serum (ATS) within 7 days and the developing fibrosarcomas could be serially propagated in ATS treated mice. The cells were also found to be susceptible to RNA tumor viruses. RD 114 and FeLV.

ATCC CCL 123 C211 (Skin. Human) Partial deletion of chromosome 4, Cri du Chat_ The C2IJ cel! line was derived by U.R. Breg in October. 1968 from a skin biopsy obtained from an 11 year-old Caucasian male with Cridu Chat Syndrome. Autoradiographic studies (Cytogenetics J: 137.1966: Am J. Human Genetics /9:399.1967) demonstrated that a distinction could be made between chromosome 4 and 5 in the Cri du Chat syndrome by alternative DNA replication pattern and length of long and short arms. The C 211 cell line (case No. 4 in 1967 reference above) has a partial deletion of the short arm of chromosome 4 (4p-) which was determined by late DNA replication pattern of the long arms of the deleted chromosome. Chromosome number 5. previously described with Cri du Chat, exhibits an early replication pattern. C 211 cells were established in McCoy's 5a medium with 20% fetal bovine serum with penicillin and streptomycin. A culture in the 5th serial subculture was submitted to the American Type Culture Collection in November. 1968.

ATCC CCL ISO A K-D_(Lung, Cat)___ The AK-D line is a clonal derivative obtained from mass cultures of fetal feline lung after passage 14 by A. Kniazeff et aL (Lab. Invest. 34:494-500.1976). Clones were initially propagated using a mixture of Eagle's MEM with 10% fetal bovine serum and a similar medium conditioned by incubation for 24 hours with feline lung cells. At passage 26 post cloning, dense membrane bound bodies with concentric lamellae were reportedly observed on examination of cell pellets by electron microscopy.
Cultures were submitted at clonal passage 20 by A. Kniazeff to the American Type Culture Collection in June. 1976. While lamellar inclusions can be observed through examination by transmission electron microscopy, these are not found in high frequency. Rates of phosphatidylcholine synthesis are less than those exhibited by fibroblasts from feline tongue (See CCL 176) or epithelia from feline kidney (See CCL 94). The line is therefore certified as indicated below, but cannot be definitively characterized as of type II origin or function.

ATCC CCL 155 RPMI 8226 (Myeloma. Human) IgG lambda-type light chain secreting_ The RPMI 8226 cell line is one of a series of human hematopoietic cell lines established by G. Moore, et al. (Proc. Soc. Exp. BioL Med. 125:1246-1250. 1967). The cells were obtained from the peripheral blood of a 61 year-old male with multiple myeloma. The Ί5 culture was initiated in RPMI medium 1640 supplemented with 10% fetal bovine serum in June 1966 and became established 66 days later. The cultured cells resembled the lymphoblastoid cells of other human lymphocyte cell lines developed from peripheral blood but no typical mature plasma cells were noted, only immature cells with deep staining cytoplasm. Immunoglobulin studies revealed that the RPMI 8226 cells produce and secrete free lambda-type light chains of immunoglobulin. No evidence was obtained either from the cells or the medium to indicate the presence of any heavy chain production. The cells secreted approximately ISug lambda-chain per 24 hours per 10* cells (45 x 107 molecules per cell per day). RPMI 8226 was shown to grow without an adaptation period in RPMI media 1640.I634and I603intheabsenceofserum(N.Y.StateJ. Med. 68:2054-2060.1968). The replication ofthe cells in chemically defined medium provides a promising means for studies relating to the synthesis of immunoglobulins.

ATCC CCL 171 MRC-S_(Lung, diploid. Human)_ The MRC-5 cell line was derived from normal lung tissue of a 14 week-old male fetus by J.P. Jacobs in September of 1966 (Nature 227:168-170.1970). The growth medium used was Eagle’s basal medium in Earle's balanced salt solution supplemented with 10% calf serum. Following the initial cultivation of the cells subcultures were prepared twice weekly at a 1:2 ratio. When the cells reached approximately the 7th cell doubling the majority of the cultures were harvested io prepare a frozen cell stock. Subsequent observations revealed the MRC-5 cells are capable of attaining 42-46 population doublings before onset of the decline in proliferation usually experienced with human fibroblast lines. Comparative studies (Proc. Symp. Human Diploid Cells, Yugoslav Acad. Sci. Ans. Zagreb.. pp. 43-55, 1970) showed that MRC-5 cells replicate more rapidly and are less sensitive to adverse environmental factors than Wl-38 cells. The MRC-5 cel) line, like WI-38 (ATCC CCL 75). is susceptible to a wide range of human viruses, is suitable for the production of viral vaccines, and has been useful in senescence studies (Nature 236:26.1972; ibid.. 239:316,1972). A culture of the MRC-5cell line was submitted to the American Type Culture Collection in the 9th passage in June. 1972.
